Performance Air Intake For Audi TT Quattro (1999-2006) with 1.8L Engine Black

Maximize Boost Efficiency for Your Audi TT Quattro 1.8T (EA113)

Who It’s For: Designed specifically for 1999-2006 Audi TT and TT Quattro owners running the legendary 1.8T (EA113) 20-valve turbocharged engine.

The Problem: The factory airbox in the 1.8T is designed for noise suppression rather than performance. It utilizes a restrictive plastic housing that creates significant air turbulence and traps heat, which can lead to increased intake air temperatures (IATs) and slower turbo spool-up. For a turbocharged engine, restricted airflow is the primary bottleneck to making more power.

The Solution: We engineered this intake to correct the factory design flaws of the 1.8T air path. By utilizing T304 lightweight aluminum piping and a high-flow filtration system, we provide a smooth, mandrel-bent path for air to reach the turbo. This reduces the workload on your K03 or K04 turbocharger, delivering reliable performance and a much more aggressive engine note.

Why This is the Ultimate Upgrade

• Increased Velocity: The smooth-bore aluminum piping reduces internal friction, allowing for up to a 10% increase in horsepower and torque by improving volumetric efficiency.
• T304 Aluminum Construction: Unlike plastic factory tubes that can crack or heat-soak, T304 aluminum dissipates heat faster and provides a permanent, durable solution for the engine bay.
• True Bolt-On Fitment: Engineered as a direct replacement for the factory air box, this kit installs in under 60 minutes with basic hand tools and requires no permanent modifications to your vehicle.
